REFRIGEBATOR.

T O aZZ whom it may conccrn: y

Be itl known that i, Jason PFLNZ, a citizen of the United States, andresident of Chicago, Illinois, (whose post-office address is at No.*0,68 touth Dcarborn strect,) have inrented certain new and usefulimprovements in Re'fri'gerators; and 1 do hereby declare that thefollowing description of my said inveniion, taken in connection with theaccompanying sheets of drawings, forms a full, clear, and eXactspecification, which will enable others slri'lled in the art to which ita'ppertains to make and use the same.

This invention has general reference to improveinents in refrigerators;and it consists, essentially, in the novel and peculiar combination ofparts and details of construction, hereinafter first fully set forth anddescribed, and then pointed out in the claim.

The object of this invention is the production of an efiicient andserviceable refr'igerator which can be used without the employnient ofice or other calorific media, the Cooling effectbeing produced by waterfiowing through a water-jacket surrounding the provision chamber. Toat'tain this effect, I construct this refrigerator as shown in thedrawings already referred to, in which Figure 1 is a perspective View ofa refrigerator `constructed in accordance with my invention. Fig. 2 is ahorizontal sectional View talen on line .2 z in Fig. 3, portions beingbroken away to disclose underlying parts. F 3 is a longitudinalsectional elevation on line a* of Fig. 2, in the direction of the arrowshown. Fig. a is a horizontal sectional riew taken on line 'y y of Fig.3.

Like parts are designated by corresponding symbols and characters ofreference in all the figures.

This refrigerator comprises an outer wooden structure A of any desireddesign or configuration, which includes one or more doors B throughwhich access can be had to the interior of theprovision Chamber O. Thislatter Chamber is a Sheet-metal structure made water-tight on all itssides, top and bottom, and it is sufficiently smaller in all of itsdimensions than the interior diniensions of the outer structure, toalford spaces D, and H, H', and H, the spaces D being separated from thespaces H, H', and H, by water-tight walls G, said spaces D havingtherein a suitable non-conductor w Specificaton of Letters Patent.

of heat E, such as char-coal, mineral wool, asbestos fiber lzc. Thewatercontaining spaces H, H', and H surround the walls of the provisionchaniber, and of these watercontaining spaces, the spaces indicated bythe reference-letter H surround three of the four Vertical wallsthereof. ln these watercontaining spaccs ll there are a series ofVcrtically disposed partitions 12, which partitions are secured to theinner metallic lining G- of the structure ;1, and to the Vertical wallsof the provision Chamber to retain the latter in position, saidpartitions 12 being perforated with a series of apertures 13,

thereby affording conununication between the several Sections of theVertical waterspaces produced by said Yertical partitions 12.

The water space H' below the provision chaniber C has longitudinalpartitions 111, and transverse partitions 15, all of which areperforated by apertures 16, said partitions lat and 15 supporting thesaid prorision Chamber O. The water-space L above the provision chaniberis likewise provided with partitions 18, and perforated with apertures19, while that portion of the Vertical walls F projecting above thetop-,plate F of the provision Chamber is perforated at various places asshown at 37 in Fig. 2, this topplate F together with the projectingportion of the Vertical walls forming, as it were, a pan which inclosesthe water space H. The Vertical partitions 12 and the projecting portionof the Vertical walls F do not reach to the top of the structure .#1butstop short thereof so as :to prevent overfiowing, there being anorerflow pipe I, leading from the water-space to carry off the heatedwater, said overfiow being suitably connected with sewer pipes, notshown.

J designates a water-supply pipe connecting the water-jacket of thisrefrigerator with any suitable source of water, there being a stop-cool:20, in this water-supply pipe J to regulate the flow of water to thewaterj acket and to turn off the water supply at any time when necessaryor desirable. This pipe J enters the water-space from above and it iscarried downwardly in one of the Vertical water-spaces H and then turnedhorizontally in the lower water-space H' which itV traverses and itterininates in a short, upwardly-turned nozzle 21. In about the middleof this pipe J there is a pipefitting 22 from the branches of which leadbranCh-pipes 23 and 2a respectively, the 1 former pipe reaching towithin a short distance of the front-wall of the structure wherein islocated the door B, while the latter reaches into approximately thecenter of the water-space H near the rear-wall and it has a short,upwardly-turned nozzle 25. In the branch pipe tthere is a pipe-fittingfrom the branch 26 of which leads a branchpipe 27 which reaches into thewater-space through which the supply-pipe J descends and whichbranch-pipe 27 has a short, upwardly-turned nozzle 28, similar to thenozzles heretofore described.

From the lower water-space H' leads a discharge-pipe K, having a faucet29, whereby the water jacket may be drained and through which sedimentsmay be removed. In the top of the wooden structure A there is a door orlid B' of usual construction, through which access may be had to thetopwater space H. In the door B leading to the provision Chamber, or inthe Vertical stile when there are two doors leading to said proVisionChamber there is located a thermometer L which indicates the temperaturein the proVision chamber. Near the upper end of the front-wall of thewooden body A there is located a register or slide 30, of approvedconstruction, which said slide serves as an adjustable inlet to anair-duct M, Figs. 2 and 3, which Connects with the interior of theprovision Chamber C to afford means for carrying off heated air. Thereis in the front wall a further register or slide 31 governing anair-passage 34, Figs 2 and 8, leading above the water-line i of theupper water-space H.

The operation of this refrigerator is substantially as follows: Vaterbeing admitted to the water-jacket surrounding the pro- Vision Chamberuntil it overflows at the overfiow I, the temperature in the proVisionChamber will be at once reduced, the walls being of metal and goodconductors of heat, until the temperature nearly approaches that of theincoming water. The upper surface of the water in the water-space Hbeing in communication with the outer atmosphere through the passage 34:and the register 31, the water wlll evaporate and thereby abstract heatfrom the surrounding objects` and reduce the temperature, additionalwater being allowed to enter through the supply-pipe J as required. Thewater in the Various Channels formed by the partitions in the severalwater-spaces will Circulate through these channels and thereby producean even temperature in the provision Chamber C. When an extremely lowtemperature is required in the provision chamber, ice may be introducedthrough the lid B' to cool off the water, and refrigerating media may beadded thereto if desired.

Having thus fully described this invention, I claim as new and desire tosecure to me by Letters Patent of the United States- A refrigeratorcomprising an outer wooden structure; an inner metallic lining; afilling of a non-Conductor of heat between the inner surface of saidwooden structure and the inner metallic lining; a prvision Chambersmaller in dimensions than thev inner metallic lining, the walls ofwhich are of watertight construction and affording spaces between theinner lining and the outer surfaces of the provision Chamber; Verticalpartitions in said spaces, said partitions being perforated and unitingthe inner lining with the Vertical walls of the provision Chamber; alower water-space, there being partitions in the latter space adapted tosupport the provision Chamber; an upper water space; a water-supply-pipeentering the Vertical water-space and passing downwardly into the lowerwater space; branches on said supply pipe entering the Vertical waterspaces, and an overfiow leading from the upper water space.

In testimony that I claim the foregoing as my invention, I have hereuntoset my hand in the presence of two subscribing witnesses.
